from urine at pH 10 in ether, indicating that neither phenylhydrazine, aniline, nor other basic metabolites were present to any significant levels. Forty-nine percent of the urinary radioactivity from TCPH (phenylhydrazine label) and 75% from TCPH (carboxyl label) was present in the acidic (pH 2.0) fraction. From cochromatography it was observed that TCPH and TAPH were not present, but 10-2090 of the radioactivity put on plate (or
